Expand description

\brief This function finishes an ongoing CMAC operation, and writes the result to the output buffer.

                 It should be followed either by
                 mbedtls_cipher_cmac_reset(), which starts another CMAC
                 operation with the same key, or mbedtls_cipher_free(),
                 which clears the cipher context.

\param ctx The cipher context used for the CMAC operation. \param output The output buffer for the CMAC checksum result.

\return \c 0 on success. \return #MBEDTLS_ERR_MD_BAD_INPUT_DATA if parameter verification fails.
